On board Water pump = outflow thru city water hookup

OH. Help. Just getting this tt set up in the driveway. Many, many little issues to resolve. Its a 2016 Surveyor 251RKS.
I've used the house supply water, with a pressure regulator = no problem. Hot water = no problem (after finding the hidden switch)

Now, when I've filled the onboard potable tank and turn on the internal water pump, it pumps water OUT the city water hook up - with the hose disconnected.

Is there a manual valve to operate? Shouldn't the internal system work automatically?

thanx

At city outlet is usually a check valve, remove screen and re-set by hand.

Removed screen - no check ball visible. Reattached city water hose and ran for a moment. Lots of pressure / water when detaching hose. Ran onboard pump. . . lots of water exiting city water connection.

Do you have proper water pressure inside when just using city water. Inline check valve might be installed backwards, stuck open, or was not installed at all.

Good pressure when on city hose water..... only when trying onboard fresh water / pump does water exit city water hook up point...

Well maybe Forest River guys did not installed proper city water inlet.....there should be a check valve at inlet. Follow city water plumbing inside trailer and see how it is piped with water pump, maybe there is a selector valve???

Must be missing something. I thought you did not use the water pump when connected to city water.

Sounds like the check valve is missing or damaged. Turn off pump, open a faucet to relieve pressure. Then remove screen and you should see a small plastic piece in there. It should be spring loaded and you should be able to push it in a short distance. There is an o-ring in there that can push pushed out of place if someone pushes it in by hand while under pressure, such as during the winterizing process.

A temporary solution would be to buy a plug that fits the threads of the fitting.

Or screw a spray nozzle on it if you have one.
